## How to know which battery your Mercedes-Benz Sls Amg takes

Easiest of all is the number plate lookup: those few characters tell us the precise variant, the engine and the original battery, so you need not check anything else.

You can also work it out yourself: find the registration date in the vehicle documents and locate it in the table. If the year overlaps two generations, the body style — hatch, estate or coupé — tells them apart.

Before ordering, inspect your existing battery: its label lists the Ah and the starting amps. The replacement must match or beat both — never fall short — and share the same size and positive terminal side.

## Start-Stop: which battery your Sls Amg needs

The later Sls Amg generations run Start-Stop, which puts the battery through hundreds of micro-cycles a day. These cars require EFB (basic Start-Stop) or AGM (Start-Stop with regenerative braking): fitting a conventional battery instead cuts service life to a few months and the ECU may disable the function. Rule of thumb: never downgrade from the technology fitted at the factory.

## Frequently asked questions

### Which battery does a Mercedes-Benz Sls Amg take?
It depends on the generation and engine: there are 2 compatible batteries in total, from 13 to 95 Ah and 200 to 850 A of cold cranking. The best sellers for this model are Start-Stop battery Varta A5 12V 95Ah 850A AGM, Car battery Varta AUX14 12V 13Ah 200A. With your plate we tell you the exact one in seconds.

### How much does a Mercedes-Benz Sls Amg battery cost?
Between 70.20 € and 179.99 €, VAT included, depending on capacity and technology (AGM). Start-Stop versions (AGM or EFB) sit at the top of the range because they withstand many more cycles.

### How do I know which generation my Sls Amg is?
By the registration year: Sls Amg Roadster (2011-2025); Sls Amg (2010-2025). If your year falls in the overlap between two generations, tell them apart by body type (hatchback, estate or coupé) or use the plate finder, which settles it with no doubt.

### Can I fit a battery with more amps?
Yes, as long as the dimensions fit the tray and the terminal layout matches. More capacity (Ah) and more cold cranking (A) do not harm the vehicle: the alternator charges it the same and you gain margin in winter. What you must never do is go below the original figures.

### How long does a Mercedes-Benz Sls Amg battery last?
Between 4 and 6 years in normal use. Start-Stop batteries (AGM/EFB) tend to last slightly less in city driving because of the number of starts, but they are designed for that cycling. If the car sits unused for weeks or you notice slow cranking in the cold, get it checked.
